Inverter Board
converts DC to AC and boosts the voltage to generate
the current necessary to power the Lamps.
Lamps
used as the primary light source are white cool-cathode
fluorescent lamps. If the light output becomes unstable, the Panel LED
flashes and the scanner enters standby mode until it becomes stable.
SUB_C Board and SUB_D Board
each contain LEDs to generate
infrared light.
